PAUL NOACRE, OF GRAND RAPIDS, MICHIGAN.

GAGE.

Specification of Letters Patent.

Patented May 1, 1906.

Application filed April 4;, 1905. Serial No. 253,900.

To all whom it may concern..-

Be it known that I, PAUL NOACRE, a citizen of the United States,residing at Grand Rapids, in the county of Kent and State of Michigan,have invented certain new and useful Improvements in Gages, of which thefollowing is a specification.

My invention relates to improvements in gages for measuring andrepairing type matrices or molds from which type are cast inlinotype-machines; and its objects are, first, to provide a gage withwhich minute difierences of size or space may be measured without in anyway changing the gage; second, to provide such a gage that willaccurately measure the distance between the lateral lugs or projectionsby which the matrix is supported in the linotype-machi'ne, and, third,to provide such a gage that will accurately measure the width of each ofthese lugs. I attain these objects by the mechanism illustrated in theaccompanying drawings, in which Figure 1 is a plan of the gage, partlyin perspective. Fig. 2 is a plan 0 a matrix.

Similar letters refer to similar parts throughout both views.

a re resents the gage, and the end between a and d tapers so graduallythat the lines 0 1 2 3 4 5 in Fig. 1 each represent a variation of, say,the one-thousandth of an inch, 0 representing the normal or absolutewidth that the matrix measures between the lugs f and g and two taperingslots, of which c is designed to measure the width of the lugs marked f,and d is designed to measure the width of the lugs marked g, and theseslots are in position to utilize the gage-lines 0 1 2 3 4 5 similar tothe end 6, except that the incline is reversed, the normal line 0representing the normal width of the respective lugs, and the successivefollowing lines indicate the amount that has been worn off of the endsof the lugs, or, in other words, how much narrower they may have worn inthousandths. The object of reducing this gage to so minute a measurementand of providing it with the three sets of minute measurements or gagesis that the matrix must be and remain exact to the minutest fraction notonly between the lugs f and g, but the lugs themselves must be keptminutely accurate in width to avert the danger of throwing the lettersout of alinement.

The imprint, impress, or mold for the letters is at the bottom of thenotches h, (see Fig. 2,) and the necessity of keeping the severalmeasurements absolutely correct is to keep these notches in their exactproper ositions, which insures perfect alinement o the letters in eachand every word, and as the wear is upon the inner edges of the lugs itis evident that any variation in the distance between the lugs mustarise from wear from the inner end of one or the other, or both, of thelugs, and when this is ascertained the lug or lugs that have been wornshort may be peened or drawn with a hammer to the proper measurements.

For the purpose of insuring accuracy of alinement I place a slot, as 'i,in the body of the gage, one edge of which will be in the exact positionto establish the perfect alinement of the letter from one end of one ofthe notches h, the distance from this slot to the edge of the gage, onthe line 0, being the exact distance that the side of the lug is fromthe line of type.

I prefer that the thickness of the plate a be exactly the same as thelength of the lugs, as by this means it will serve as a gage forinsuring the proper length of the lugs when readjusting them.

Having thus fully described my'invention, what I claim as new, anddesire to secure by Letters Patent, is

In a gage for measurin matrices for linotype-machines, a thin plateuniformly tapered, edgewise, toward the end and having slots uniformlytapered toward the opposite direction, and alined graduations indicatingthe measurements both at the ed es of the plate and in the slots,substan'tia y as and for the purpose set forth.

Signed at Grand Rapids, Michigan, March 22, 1905.
